Coloured angiogram X-ray (anterior oblique view) of the blood vessels of the heart in a male patient aged 65, showing staged aortic aneurysm (dark red, centre right). The heart is at lower centre (yellow). The aorta is the main artery (upper centre curving round) that transports blood from the heart to the body. Here, it has bulged in size in stages (aneurysm) due to a weakening of the artery wall. The patient was diagnosed with arterial hypertension.
